When replacing a faulted device which was previously handled by a spare
multiple levels of nested interior VDEVs will be present in the pool
configuration; the following example illustrates one of the possible
situations:
NAME STATE READ WRITE CKSUM
testpool DEGRADED 0 0 0
raidz1-0 DEGRADED 0 0 0
spare-0 DEGRADED 0 0 0
replacing-0 DEGRADED 0 0 0
/var/tmp/fault-dev UNAVAIL 0 0 0 cannot open
/var/tmp/replace-dev ONLINE 0 0 0
/var/tmp/spare-dev1 ONLINE 0 0 0
/var/tmp/safe-dev ONLINE 0 0 0
spares
/var/tmp/spare-dev1 INUSE currently in use
This is safe and allowed, but get_replication() needs to handle this
situation gracefully to let zpool add new devices to the pool.
